Blood-sucking leeches use their anterior suckers to connect to hosts for feeding. Once attached, they use a combination of mucus and suction to stay in place while they inject hirudin into the hosts' blood. In general, blood-feeding leeches are non host-specific, and do little harm to their host, dropping off after consuming a blood meal. Some ...
Glossiphoniidae are a family of freshwater proboscis-bearing leeches. These leeches are generally flattened, and have a poorly defined anterior sucker . Most suck the blood of freshwater vertebrates like amphibians , crocodilians and aquatic turtles , but some feed on invertebrates like oligochaetes and freshwater snails instead.
Well-known Haemadipsidae are for example the Indian Leech (Haemadipsa sylvestris) and the yamabiru or Japanese Mountain Leech (Haemadipsa zeylanica). Members of the family feed on blood, except Idiobdella which has adapted to eat small snails. [1] The other notable group of jawed blood-sucking leeches are the aquatic Hirudinidae.
The leeches engorge themselves with blood before mating. One or two months after feeding, the leeches produce spongy cocoons, which are pale yellow and elliptical in shape. About another month later, the young, only 20 to 22 millimetres (0.79 to 0.87 in) long, emerge. [7]: 68 They take several years to become fully mature. [23]
Haementeria ghilianii is a species of leech in the Glossiphoniidae family, comprising freshwater proboscis-bearing leeches. Colloquially, they are known as the Amazon giant leech . Following its initial description in 1849, additional details were provided based on specimens from French Guiana in 1899, after which the species was largely ...
The volume of blood consumed at any one time is much smaller than is typical for the European medicinal leech, but L. nilotica may stay in place for several weeks, feeding at intervals. [ 4 ] Limnatis nilotica is periodically reported as affecting humans and livestock, entering the host through the mouth, nose, and occasionally through the eye ...
This is the adorable moment parent toucans feed their young at a wildlife park in Japan. Footage shows the toucan family taking a meal together, with the larger birds handing over scraps of food ...
Terrestrial leeches primarily feed on mammals, though the New Zealand species have adapted to rely on birds. The Open Bay Islands leech feeds primarily on the feet of nesting seabirds, especially Fiordland penguins (Eudyptes pachyrhynchus). Leeches are able to ingest several times their body weight in blood, and can take months to digest it. [4]
